TL;DR: TIMP-resistant, active MMP-8 expressed on the surface of activated PMN is likely to be an important form of M MP-8, regulating lung inflammation and collagen turnover in vivo.
Abstract: Little is known about the cell biology or the biologic roles of polymorphonuclear cell (PMN)-derived matrix metalloproteinase-8 (MMP-8). When activated with proinflammatory mediators, human PMN release only approximately 15-20% of their content of MMP-8 ( approximately 60 ng/10(6) cells) exclusively as latent pro-MMP-8. However, activated PMN incubated on type I collagen are associated with pericellular collagenase activity even when bathed in serum. PMN pericellular collagenase activity is attributable to membrane-bound MMP-8 because: 1) MMP-8 is expressed in an inducible manner in both pro- and active forms on the surface of human PMN; 2) studies of activated PMN from mice genetically deficient in MMP-8 (MMP-8(-/-)) vs wild-type (WT) mice show that membrane-bound MMP-8 accounts for 92% of the MMP-mediated, PMN surface type I collagenase activity; and 3) human membrane-bound MMP-8 on PMN cleaves types I and II collagens, and alpha(1)-proteinase inhibitor, but is substantially resistant to inhibition by tissue inhibitor of metalloproteinase-1 (TIMP-1) and TIMP-2. Binding of MMP-8 to the PMN surface promotes its stability because soluble MMP-8 has t(1/2) = 7.5 h at 37 degrees C, but membrane-bound MMP-8 retains >80% of its activity after incubation at 37 degrees C for 18 h. Studies of MMP-8(-/-) vs WT mice given intratracheal LPS demonstrate that 24 h after intratracheal LPS, MMP-8(-/-) mice have 2-fold greater accumulation of PMN in the alveolar space than WT mice. Thus, MMP-8 has an unexpected, anti-inflammatory role during acute lung injury in mice. TIMP-resistant, active MMP-8 expressed on the surface of activated PMN is likely to be an important form of MMP-8, regulating lung inflammation and collagen turnover in vivo.

TL;DR: In this article, the authors studied the localization properties of weak solutions to the Dirichlet problem for the degenerate parabolic equation u t - div ( | u | γ ( x, t ) ∇ u ) = f, with variable exponent of nonlinearity γ.
Abstract: We study the localization properties of weak solutions to the Dirichlet problem for the degenerate parabolic equation u t - div ( | u | γ ( x , t ) ∇ u ) = f , with variable exponent of nonlinearity γ . We prove the existence and uniqueness of weak solutions and establish conditions on the problem data and the exponent γ ( x , t ) sufficient for the existence of such properties as finite speed of propagation of disturbances, the waiting time effect, finite time vanishing of the solution. It is shown that the solution may instinct in a finite time even if γ ≡ γ ( x ) ⩽ 0 in the problem domain but max γ = 0 .

TL;DR: Using targeted enrichment of mitochondrial DNA, it is shown that cave sediments represent a rich source of ancient mammalian DNA that often includes traces of hominin DNA, even at sites and in layers where no Hominin remains have been discovered.
Abstract: Although a rich record of Pleistocene human-associated archaeological assemblages exists, the scarcity of hominin fossils often impedes the understanding of which hominins occupied a site. Using targeted enrichment of mitochondrial DNA, we show that cave sediments represent a rich source of ancient mammalian DNA that often includes traces of hominin DNA, even at sites and in layers where no hominin remains have been discovered. By automation-assisted screening of numerous sediment samples, we detected Neandertal DNA in eight archaeological layers from four caves in Eurasia. In Denisova Cave, we retrieved Denisovan DNA in a Middle Pleistocene layer near the bottom of the stratigraphy. Our work opens the possibility of detecting the presence of hominin groups at sites and in areas where no skeletal remains are found.
